WebApr 1, 2024 · Asymmetric transmission (AT) refers to the phenomenon that EM can pass through a special structure plate in one direction and be blocked in the reverse direction. Contrary to the irreversibility of the Faraday effect, AT is produced by the interaction of EM radiation with a unique chiral metamaterials (CMMs) structure [[6], [7], [8] ]. WebDec 1, 2024 · Asymmetric transmission. In order for a chiral MS to exhibit AT, it must lack C4 (90 0 rotational) symmetry and C2 (180 0 rotational) symmetry. This is however a necessary condition and not sufficient. A single layer planar chiral MS cannot exhibit AT as it will appear the same for both the forward and backward directions of propagation.
